NOTES

This l)1ap is for use in administering the National Flood Insurance Program;
it do~s not necessarily identify all areas subject to flooding. particularly from
local lprainage sources of small size. or all planimetric features outside
Special Flood Hazard Areas.

Coast~1 base flood elevations apply only landward of 0.0 NGVD. and include
the effects of wave action; these elevations may also differ significantly
from those developed by the National Weather Service for hurricane
evacuation planning.

Areasiof Special Flood Hazard (10o-year flood) include Zones A. AE. AH. AO,
A99. Y. and VE.

'\5,\SI AVENUE

Certain areas not in Special Flood Hazard Areas may be protected by
flood . control structures.

Boundaries of the floodways were computed at cross sections and
interpblated between cross sections. The floodways were based on
hydra&lic considerations with regard to requirements of the Federal
Emerdency Management Agency.

Floodyvay widths in some areas may be too narrow to show to scale.
Floodway widths are provided in the Flood Insurance Study Report.

This !T1ap may incorporate approximate boundaries of Coastal Barrier
Resource System Units and lor Otherwise Protected Areas established
under the Coastal Barrier Improvement Act of 1990 (PL 101-591).

Corporate limits shown are current as of the date of this map. The user
should contact appropriate community officials to determine if corporate
limits have changed subsequent to the issuance of this map.
